Only a few herds of reindeer and caribou are increasing or are stable at high numbers; most herds continue to decline or remain at low numbers after severe declines in recent decades. Whether these trends are a result of Arctic climate change or part of a natural pattern is still unknown.

Nearly ten percent of U.S. watersheds are living beyond their means when it comes to their water supply. For nearly half the country, water stress is projected to worsen by mid-century because of climate change, according to a recent NOAA-funded analysis.

The most likely explanation for the lack of significant warming at the Earth’s surface in the past decade or so is that natural climate cycles caused shifts in ocean circulation patterns that moved some excess heat into the deep ocean.

Stunned by Sandy's devastation, the city of New York undertook an ambitious project: to update its long-term sustainability plan using the latest climate science. Their goal was to understand how much sea level could rise, how soon, and just how vulnerable the city would be if some of the more extreme climate change projections turn into reality.

Developed by the NOAA Coastal Services Center, the sea level rise viewer offers access to data and information about the risks of sea level rise, storm surge, and flooding along the coastal United States. The Web-based map has the potential to help people build (or rebuild) in a more resilient way.

While heat is stored and mixed throughout the depth of the ocean, it is the temperature at the surface—where the ocean is in direct contact with the atmosphere—that plays a significant role in weather and short-term climate.

Where are the best places to live if you are looking to avoid tropical cyclones? By mapping out data from the IBTrACS historical storm database, we can see where tropical cyclones make landfall most frequently and where the most intense storms tend to gravitate in the western hemisphere.
